Baloney. I don't think it's "black magic", but as a software engineer with some deep familiarity with my tool chain I'm not going to pretend that I could ever be as productive as some of these folks. It's like when I see another post about a Fabrice Bellard project, and I think "he gets done in a year what it would take me about a career".
I don't understand this fetishization of "everyone has nearly equal ability" in the face of tons of overwhelming evidence to the contrary.
